The Mono Bob Is Set to Be Autumn 2025’s Biggest Hair Trend

If you ask me, autumn is the time of the year when polished haircuts come into their own. And when it comes to bob trends, one thing I’ve noticed as a beauty editor who studies hair trends for a living is that every autumn/winter, short haircuts get more structured.

In summer, we tend to opt for low-maintenance hairstyles and beachy waves while embracing our natural hair texture. But for autumn, just as we tend to call upon more structured silhouettes from coats and tailoring in our wardrobes, our hair typically follows suit. And that’s the case with the latest bob trend I’ve seen bubbling up for the season ahead: The mono bob.

Like a blunt bob, the mono bob features the same characteristics with razor-sharp ends, but coupled with hair that is all one length for a clean silhouette, coupled with natural, lived-in texture. What the mono bob presents is a one-length style with slightly softened ends. Unlike the highly layered bobs and bouncy shapes we’ve seen in recent years, this bob cut features no layers, resulting in an ultra-polished shape, whether it’s a lob length, a chin-length bob, or gently skimming the shoulders.

If you’re thinking of getting braids for autumn, why not consider having a protective style in a bob length?
